MOP.

Application filed April l, 1918.

To all whom it may concern.-

Be it known that I, EDWARD H; TATE, a

citizen'of the United States, residing at alden, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Mops, of which the following is a specification.

Thisinvention relates to a mop comprising an externally channeled sheet metal frame, a flexible mop element comprising a neck clamped on the channeled side of depending frame. The object of the invention is to provide improved handle-engaging means of simple, strong, and durable character.

he invention is embodied in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is a top plan view of a bodying the invention, a portion of the frame being shown in section. V

Fig. 2 is a side view of the mop, another portion of the frame being shown in section.

Fig. 3 is a section on line 8-3 of ig. l.

Fig. 4 is a perspective view of a portion of the frame.

Fig. 5 is a section on line 55 of Fig. 4.

Fig. 6 is a plan view of the frame-and handle-engaging bar hereinafter described.

' Fig. 7 is a plan view showing a different form of frame.

he same reference characters indicate the same parts in all of the figures.

12 represents a frame composed of a channeled strip of sheet metal, one side of the strip being concave, and theconcave side forming the outer side of the frame. 'The strip is bent to form a frame of suitable form and its ends 12 are overlapped to form a slip joint, permitting the frame to be expanded and contracted. The preferred form of the frame is triangular, as shown by Fig. 1, although the frame may be circular, as shown by Fig. 7.

A flexible mop element is clamped upon the outer side of the frame, said element including a flexible neck 13 and fibrous filaments 14 depending therefrom. The neck is secured to the frame by suitable means such as a wire ligature 15, arranged to press mop em- 7 Specification of Letters Patent.

portions of the neck into the channel of the frame, as indicated by Fig. 2.

he frame is provided at opposite sides with orifices 16, these being formed in inwardly projecting bosses 17 when the frame is triangular, the faces of the two bosses in which the orifices 16 are formed being parallel with each other, as indicated by Fig. 1.

18 designates a bar formed to extend across the frame from one apertured portion thereof to the other, said bar being provided at its ends with reduced trunnions 19 formed to enter and turn in the orifices 16. The ends of the bar form shoulders 20 bearing on portions of the inner surface of the frame, said portions being parts of the bosses 17 when the frame is triangular.

The bar 18 is provided with a handle-enengage a tapped handle being shown by dotted lines in Figs. 1 and 2.

the bosses 17, The said heads are preferably adjustable relatively to each other, to regulate the frictional contact between the shoulders 20 of the bar 18 and the portions of the inner surface of the frame on which they hear. The heads are preferably nuts 23, the trunnions 19 being screw-threaded to engage said nuts.

The slip joint formed by the overlapping ends 12 of the frame permits a sufficient exof the trunnions 19 in the operation being performed before the flexible mop element is applied to the frame. The nuts 23 are then set up to press portions of the frame against the shoulders 20 of the bar 18, after which the flexible mop element is applied and secured by the ligature 15.

The nuts 23 are preferably set up with sufficient force to create a suitable frictional contact between the shoulders 20 and the apertured portions of the frame and thus prevent the frame from swinging too loosely on the trunnions. To provide for subsequent setting up of the nuts, without removing the flexible mop element, I provide one of 19 with a right hand screw thread, and the other with a left hand screw thread, the nuts 23 being correspondingly tapped. This construction enables the-bar 18 to be rotated within the frame, the handle I the apertured portions of the frame.

When the bar 18 is rotated for the purpose stated-,the nuts 23 may be prevented from rotating with the bar by the side portions of the bosses 17 shown by Fig. 3, said portions being in sufliciently close proximity to opposite edges of the nuts as shown by Fig.

against rotation with 3, to confine the nuts the bar. Said side portions are suliiciently flexible to enable them to yield slightly to force exerted on the vnuts in screwing them to place on the trunnions, when the bar is held stationary.

When the frame is circular, as shown by Fig. 7 the neck 13 of the mop element bears on the outer sides of the nuts with sufficient pressure to prevent them from turning with the bar 18.

Ihe bar 18 and its trunnions 19 and shank prising a neck clamped on the channeled side of the frame and fibrous filaments depending from said neck, a rotatable trans verse bar having a handle-engaging shank at its central portion and bearing at its ends on portions of the internal surface of the 7 frame, said bar being provided with trunnlons inserted in said orifices, and oppositely screw threaded, and correspondingly tapped nuts engaged with said trunnions and constituting heads which bear OIlPOltlODS of the external surface of the frame, and are adjustable simultaneouslyin opposite directions by rotation of the bar and trunnions, means being provided for preventing rotation of the nuts with the bar.

In testimony whereof I have affixed my signature.
